A certain PC (Personal Computer) 40 is provided. The MFP 20 and the server 30 are communicably connected to each other via a network 11 such as a LAN (Local Area Network) or the Internet. Similarly, the MFP 20 and the PC 40 are connected to be communicable with each other via the network 11.

  FIG. 2 is a block diagram of the MFP 20.

  As shown in FIG. 2, the MFP 20 is a display device such as an operation unit 21 that is an input device such as buttons for inputting various operations by the user and an LCD (Liquid Crystal Display) that displays various information. A display unit 22, a scanner 23 that is a reading device that reads an image from a document, a printer 24 that is a printing device that executes printing on a recording medium such as paper, an external facsimile apparatus (not shown), a public telephone line, and the like A fax communication unit 25 that is a fax device that performs fax communication via a communication line, a network communication unit 26 that is a network communication device that communicates with an external device via the network 11 (see FIG. 1), and various data. Stored EEPROM (Electrically rasable Programmable Read Only Memory), an HDD (Hard Disk Drive) storage unit 27 is a storage device such as, and a control unit 28 which controls the entire MFP 20.

  The operation unit 21 may include an input device that forms a touch panel together with the display unit 22.

  The storage unit 27 stores a log image generation program 27a executed by the MFP 20 as the computer of the present invention. The log image generation program 27a may be installed in the MFP 20 at the manufacturing stage of the MFP 20, or may be additionally installed in the MFP 20 from a storage medium such as an SD card or a USB (Universal Serial Bus) memory. It may be additionally installed in the MFP 20 from above.

  The storage unit 27 can store login information 27b that is a combination of a user ID and a password.

  The storage unit 27 can store a plurality of job logs 27c. The job log 27c includes a log image 27d as a history of images to be processed in the job. The log image 27d is, for example, image data in PDF (Portable Document Format) format.

  The storage unit 27 also includes log image guarantee level information 27e indicating a level for guaranteeing the log image 27d (hereinafter referred to as “log image guarantee level”) and the resolution of the log image 27d (hereinafter referred to as “log image resolution”). And log image resolution information 27f indicating ".)".

  The control unit 28 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores programs and various data in advance, and a RAM (Random Access Memory) used as a work area of the CPU. ing. The CPU is configured to execute a program stored in the ROM or the storage unit 27.

  The control unit 28 executes a log image generation program 27a stored in the storage unit 27, thereby determining a job type determination unit 28a for determining the job type of the MFP 20, and a log image generation unit for generating a job log image 27d. 28b and the level receiving means 28c that receives the log image guarantee level.

  For example, as a job, “copy” in which an image read from a document by the scanner 23 is printed on a recording medium by the printer 24, and an image read from the document by the scanner 23 by the network communication unit 26 by the PC 40 (see FIG. 1). “Transmission” to be transmitted to a device outside the MFP 20, “Print” in which an image based on print data received from the device outside the MFP 20 such as the PC 40 by the network communication unit 26 is printed on a recording medium by the printer 24, and the MFP 20. There is “FAX reception printing” in which an image based on print data received by a facsimile communication unit 25 from an external facsimile machine is printed on a recording medium by a printer 24.

  Here, in the “send” job, images generated from the same manuscript are transmitted using a plurality of communication methods such as FAX, e-mail, FTP (File Transfer Protocol), and SMB (Server Message Block). An information transmission job is included. The heterogeneous broadcast transmission job includes a heterogeneous heterogeneous broadcast transmission job in which a plurality of communication methods in which at least one of the color and resolution of the image to be transmitted is different from each other. ing. In the MFP 20, the color and resolution of the image to be transmitted in the case of transmission by a communication method other than FAX in one heterogeneous broadcast transmission job are the same. In other words, the different image heterogeneous broadcast transmission job in the MFP 20 is a heterogeneous broadcast transmission job that transmits by a FAX communication method and a communication method other than FAX.

  For example, “204 dpi × 98 dpi”, “204 dpi × 196 dpi”, “204 dpi × 391 dpi”, “408 dpi” may be used as the resolution of an image to be transmitted (hereinafter referred to as “FAX transmission resolution”) when the MFP 20 transmits by FAX. X391 dpi "can be specified. In addition, for example, “200 dpi × 100 dpi”, “200 dpi × 200 dpi”, “200 dpi” may be used as the resolution of an image to be transmitted (hereinafter referred to as “Other transmission resolution”) when the MFP 20 transmits by a communication method other than FAX. “× 400 dpi”, “300 dpi × 300 dpi”, “400 dpi × 400 dpi”, and “600 dpi × 600 dpi” can be designated. Here, in “204dpi × 98dpi”, the front resolution “204dpi” represents the vertical resolution of the image, and the rear resolution “98dpi” represents the horizontal resolution of the image. . "204dpi x 196dpi", "204dpi x 391dpi", "408dpi x 391dpi", "200dpi x 100dpi", "200dpi x 200dpi", "200dpi x 400dpi", "300dpi x 300dpi", "400dpi x 400dpi" and "600dpi" The same applies to “× 600 dpi”.

  When the MFP 20 transmits by FAX, the color of the image to be transmitted is monochrome. In addition, the MFP 20 can specify color or monochrome as the color of the image to be transmitted when transmitting by a communication method other than FAX. Note that the MFP 20 may be able to designate color or monochrome as the color of the image to be transmitted when transmitting by FAX.

  Note that the control unit 28 sets the capacity for storing the job log 27c in the storage unit 27 to the upper limit number (for example, 200) of the job log 27c and the total upper limit size (for example, all job logs 27c). 10 GB, etc.). The number of job logs 27c stored in the storage unit 27 reaches the upper limit number, or the total size of all job logs 27c stored in the storage unit 27 reaches the upper limit size. Is a state in which the free space for storing the job log 27c does not remain in the storage unit 27 (hereinafter referred to as “log full state”). Note that the control unit 28 can set the upper limit number and the upper limit size by the administrator of the MFP 20 via the operation unit 21, for example.

  Next, the operation of the image forming system 10 will be described.

  First, the operation of the MFP 20 when receiving designation of the log image guarantee level will be described.

  FIG. 3 is a flowchart of the operation of the MFP 20 when receiving designation of the log image guarantee level.

  When the administrator of the MFP 20 instructs the MFP 20 via the operation unit 21 to start the operation when accepting the designation of the log image guarantee level, the control unit 28 of the MFP 20 executes the operation shown in FIG.

  As shown in FIG. 3, the level accepting unit 28c of the control unit 28 causes the display unit 22 to display the log image guarantee level designation screen 50 shown in FIG. 4 for accepting designation of the log image guarantee level (S201).

  FIG. 4 is a diagram illustrating an example of the log image guarantee level designation screen 50.

  The log image guarantee level designation screen 50 shown in FIG. 4 includes a radio button 51 for allowing the administrator to select the log image guarantee level via the operation unit 21. As log image assurance levels that can be selected by the radio button 51, for example, there are “low level” and “high level”. Here, the “low level” is a level where emphasis is placed on the job being executed rather than the log image 27d being left, and the job is executed even in the log full state. On the other hand, the “high level” is a level in which the log image 27d is more important than the job being executed, and the job is not executed in the log full state. That is, the “high level” has a higher security level than the “low level” in terms of leaving the log image 27d. Note that the initial value of the log image guarantee level is, for example, “low level”.

  The log image guarantee level designation screen 50 includes a button 52 for accepting specification of the log image guarantee level and a button 53 for canceling acceptance of designation of the log image guarantee level.

  As shown in FIG. 3, the level receiving unit 28c determines whether or not a log image guarantee level has been designated after the process of S201 (S202). Here, the level receiving unit 28c determines that the log image guarantee level is designated when the button 52 is pressed via the operation unit 21 on the log image guarantee level designation screen 50.

  If the level accepting unit 28c determines in S202 that the log image guarantee level is not designated, it determines whether or not the designation of the log image guarantee level is stopped (S203). Here, the level receiving unit 28c determines that the designation of the log image guarantee level has been stopped when the button 53 is pressed via the operation unit 21 on the log image guarantee level designation screen 50.

  If the level accepting unit 28c determines in S203 that the specification of the log image guarantee level has been stopped, the operation shown in FIG.

  On the other hand, when the level receiving unit 28c determines in S203 that the designation of the log image guarantee level has not been stopped, the level receiving unit 28c returns to the process of S202 again.

  When the level accepting unit 28c determines in S202 that the log image guarantee level has been designated, the setting selected by the radio button 51 is written in the storage unit 27 as the log image guarantee level information 27e (S204), as shown in FIG. End the operation.

  Next, the operation of the MFP 20 when receiving designation of the log image resolution will be described.

  FIG. 5 is a flowchart of the operation of the MFP 20 when receiving designation of the log image resolution.

  When the administrator of the MFP 20 instructs the MFP 20 via the operation unit 21 to start the operation when accepting the designation of the log image resolution, the control unit 28 of the MFP 20 executes the operation shown in FIG.

  As shown in FIG. 5, the control unit 28 causes the display unit 22 to display the log image resolution designation screen 60 shown in FIG. 6 for accepting designation of the log image resolution (S211).

  FIG. 6 is a diagram illustrating an example of the log image resolution designation screen 60.

  A log image resolution designation screen 60 shown in FIG. 6 includes a radio button 61 for allowing the administrator to select the log image resolution via the operation unit 21. Examples of log image resolutions that can be selected by the radio button 61 include “72 dpi × 72 dpi”, “100 dpi × 100 dpi”, “200 dpi × 200 dpi”, and “300 dpi × 300 dpi”. Here, in “72 dpi × 72 dpi”, the front resolution represents the vertical resolution of the log image 27 d, and the rear resolution represents the horizontal resolution of the log image 27 d. The same applies to “100 dpi × 100 dpi”, “200 dpi × 200 dpi”, and “300 dpi × 300 dpi”. Note that the initial value of the log image resolution is, for example, “200 dpi × 200 dpi”.

  The log image resolution designation screen 60 includes a button 62 for accepting designation of the log image resolution and a button 63 for canceling acceptance of designation of the log image resolution.

  As shown in FIG. 5, the control unit 28 determines whether or not the log image resolution is designated after the process of S211 (S212). Here, the control unit 28 determines that the log image resolution is designated when the button 62 is pressed via the operation unit 21 on the log image resolution designation screen 60.

  When determining in S212 that the log image resolution is not designated, the control unit 28 judges whether or not the designation of the log image resolution is stopped (S213). Here, the control unit 28 determines that the designation of the log image resolution has been stopped when the button 63 is pressed via the operation unit 21 on the log image resolution designation screen 60.

  If the control unit 28 determines in S213 that the designation of the log image resolution has been stopped, the operation illustrated in FIG.

  On the other hand, if the control unit 28 determines in S213 that the designation of the log image resolution has not been stopped, the control unit 28 returns to the process of S212 again.

  When determining in S212 that the log image resolution has been designated, the control unit 28 writes the setting selected by the radio button 61 into the storage unit 27 as the log image resolution information 27f (S214), and ends the operation shown in FIG. To do.

  Next, the operation of the MFP 20 when the user logs in will be described.

  FIG. 7 is a flowchart of the operation of the MFP 20 when the user logs in.

  When the user instructs the MFP 20 via the operation unit 21 to start the operation for accepting login, the control unit 28 of the MFP 20 executes the operation shown in FIG.

  As shown in FIG. 7, the control unit 28 causes the display unit 22 to display the login screen 70 shown in FIG. 8 for accepting login (S231).

  FIG. 8 is a diagram illustrating an example of the login screen 70.

  The login screen 70 shown in FIG. 8 is used to allow the user to input the user ID via the operation unit 21 and the text box 71 for allowing the user to input the user ID via the operation unit 21. A text box 72, a button 73 for accepting a login instruction, and a button 74 for canceling acceptance of the login instruction.

  As shown in FIG. 7, the control unit 28 determines whether or not login has been instructed after the process of S231 (S232). Here, the control unit 28 determines that login is instructed when the button 73 is pressed via the operation unit 21 on the login screen 70.

  If it is determined in S232 that login is not instructed, the control unit 28 determines whether or not the login instruction is stopped (S233). Here, the control unit 28 determines that the login instruction is stopped when the button 74 is pressed on the login screen 70 via the operation unit 21.

  If the control unit 28 determines in S233 that the login instruction has been canceled, the operation illustrated in FIG.

  On the other hand, when determining in S233 that the login instruction has not been canceled, the control unit 28 returns to the process of S232 again.

  When determining in S232 that login has been instructed, the control unit 28 determines whether or not the combination of ID and password specified in the text box 71 and the text box 72 is included in the login information 27b on the storage unit 27. Judgment is made (S234).

  When the control unit 28 determines in S234 that the combination of ID and password specified in the text box 71 and the text box 72 is not included in the login information 27b, the control unit 28 causes the display unit 22 to display a login failure. (S235), the process returns to S231 again.

  On the other hand, when the control unit 28 determines in S234 that the combination of the ID and password specified in the text box 71 and the text box 72 is included in the login information 27b, this ID is used as an administrator ID for login. It is determined whether or not it is included in the information 27b (S236).

  If the control unit 28 determines in S236 that the login information 27b is included as the administrator ID in S236, the control unit 28 permits the login as the administrator (S237) and ends the operation shown in FIG.

  On the other hand, when the control unit 28 determines in S236 that the login information 27b is not included as the manager ID, the storage unit 27 determines whether or not the currently set log image guarantee level is “high level”. A determination is made based on the log image assurance level information 27e above (S238).

  If the control unit 28 determines in S238 that the currently set log image guarantee level is not “high level”, the control unit 28 permits login as a user (S239), and ends the operation shown in FIG.

  On the other hand, when it is determined in S238 that the currently set log image guarantee level is “high level”, the control unit 28 determines whether or not the log full state is set (S240).

  When it is determined in S240 that the log is in the log full state, the control unit 28 causes the display unit 22 to display the log full state login error screen 80 shown in FIG. 9 for notifying the user that login is not permitted in the log full state. After that (S241), the operation shown in FIG.

  On the other hand, if it is determined in S240 that the log is not full, the control unit 28 permits login as a user (S239) and ends the operation shown in FIG.

  In the above, the operation of the MFP 20 when the user logs in by inputting the ID and password via the operation unit 21 has been described. However, the login method is not limited to this. For example, the MFP 20 includes a card reader, and after the user is authenticated by holding the IC card for login of the user over the card reader, the processing of S236 to S241 is executed. good. The MFP 20 displays the login screen 70 shown in FIG. 8 when the processing of S236 to S241 is executed by the user authentication by holding the IC card for login of the user over the card reader. Instead, the processing of S236 to S241 may be executed.

  In the above description, the login to the MFP 20 via the operation unit 21 has been described. However, it is also possible to log in to the MFP 20 from the PC 40 via the network 11. When logging in to the MFP 20 from the PC 40 via the network 11, the display in S <b> 231, S <b> 235 and S <b> 241 is displayed on the display unit of the PC 40.

  Next, the operation of the MFP 20 when executing a job when the user is logged in will be described.

  FIG. 10 is a flowchart of the operation of the MFP 20 when executing a job when the user is logged in.

  When executing a job when the user is logged in, the control unit 28 of the MFP 20 performs the operation shown in FIG.

  As shown in FIG. 10, the control unit 28 determines whether or not the log is full (S261).

  When determining in S261 that the log is in the full state, the control unit 28 determines whether or not the job to be executed (hereinafter referred to as “target job”) is a “FAX reception print” job (S262). The reason that only the “FAX reception printing” job is handled specially is that the “FAX reception printing” job does not require login in the first place. This is because the “FAX reception printing” job is normally transmitted from a person other than the user of the MFP 20, and therefore it is necessary to guarantee the execution of the job.

  When determining in S262 that the target job is not a “FAX reception print” job, the control unit 28 determines the currently set log image assurance level based on the log image assurance level information 27e in the storage unit 27 ( S263).

  If the control unit 28 determines in S262 that the target job is a job of “FAX reception printing” or determines in S263 that the currently set log image guarantee level is “low level”, the control unit 28 The oldest job log 27c is deleted (S264), and a log full status warning screen 91 shown in FIG. 11 for notifying the user that the log is full is displayed on the display unit 22 (S265).

  When the control unit 28 determines in S261 that the log is not full or executes the process of S265, the control unit 28 executes the target job (S266).

  Next, the control unit 28 generates a job log 27c for the target job (S267), saves the generated job log 27c in the storage unit 27 (S268), and ends the operation illustrated in FIG.

  When the control unit 28 determines in S263 that the currently set log image guarantee level is “high level”, the log full shown in FIG. 12 for notifying the user that the job execution is to be stopped in the log full state. The status job error screen 92 is displayed on the display unit 22 (S269), and the execution of the target job is stopped (S270).

  Next, the control unit 28 displays the log full state forced logout notification screen 93 shown in FIG. 13 for notifying the user that logout is forcibly performed in the log full state on the display unit 22 (S271), and then displays the user. The user logs out (S272) and ends the operation shown in FIG.

  In the above description, the case where the MFP 20 is instructed to execute a job via the operation unit 21 has been described. However, the PC 20 can also instruct the MFP 20 to execute a job via the network 11. . When the execution of a job is instructed from the PC 40 to the MFP 20 via the network 11, the display in S265, S269, and S271 is displayed on the display unit of the PC 40.

  Further, in order to notify the administrator that the log is full, the MFP 20 notifies the administrator by e-mail or the like instead of the display in S265 or in addition to the display in S265 in S265, for example. It may be designed to execute.

  The job log 27c stored in the storage unit 27 as described above is transmitted to the server 30 by the control unit 28 via the network communication unit 26 at a preset time. Then, the server 30 accumulates the job log transmitted from the MFP 20. The control unit 28 of the MFP 20 deletes the job log 27c that has been successfully transmitted to the server 30 from the storage unit 27, and stores the job log 27c that has failed to be transmitted to the server 30 due to a communication error or the like in preparation for the next transmission. Part 27 is left.

  The server 30 extracts text data in the log image by executing OCR (Optical Character Recognition) on the log image of the accumulated job log, and then violates the security policy in the text data. When it is detected that a keyword is included, the administrator is notified by a method such as e-mail.

  Next, the operation of the MFP 20 when generating the log image 27d in the generation of the job log 27c in S267 will be described.

  FIG. 14 is a flowchart of the operation of the MFP 20 when the log image 27d is generated in the generation of the job log 27c in S267.

  As shown in FIG. 14, the job type determination unit 28a of the control unit 28 determines whether or not the target job is a different image different type broadcast transmission job (S301). The reason that only the different image heterogeneous broadcast transmission job is specially handled is that the job other than the different image heterogeneous broadcast transmission job has only one type of image as the basis of the log image 27d.

  When the log image generation unit 28b of the control unit 28 determines in S301 that the target job is a different image / different broadcast transmission job, it determines whether or not “low level” is set in the log image guarantee level information 27e. Judgment is made (S302).

  When the log image generation unit 28b determines in S302 that “low level” is not set in the log image guarantee level information 27e, the FAX transmission resolution of the different image heterogeneous broadcast transmission job that is the target job is the log image resolution information. It is determined whether or not the log image resolution (hereinafter referred to as “system resolution”) set in 27f is exceeded (S303).

  Here, the log image generation unit 28b has a vertical resolution of the FAX transmission resolution equal to or higher than the vertical resolution of the system resolution, and a horizontal resolution of the FAX transmission resolution is equal to or higher than the horizontal resolution of the system resolution. In this case, it is determined that the FAX transmission resolution is equal to or higher than the system resolution. On the other hand, the log image generation unit 28b determines that the vertical resolution of the FAX transmission resolution is lower than the vertical resolution of the system resolution, or the horizontal resolution of the FAX transmission resolution is lower than the horizontal resolution of the system resolution. In some cases, it is determined that the FAX transmission resolution is less than the system resolution.

  When the log image generation unit 28b determines in S303 that the FAX transmission resolution is lower than the system resolution, the log image generation unit 28b calculates a minus difference amount F of the FAX transmission resolution with respect to the system resolution (S304).

  FIG. 15 is a flowchart of the operation of the MFP 20 when the minus difference amount F is calculated in S304.

  As illustrated in FIG. 15, the log image generation unit 28b of the control unit 28 obtains a value obtained by subtracting the vertical resolution of the system resolution from the vertical resolution of the FAX transmission resolution (S331).

  Next, the log image generation unit 28b obtains a value obtained by subtracting the horizontal resolution of the system resolution from the horizontal resolution of the FAX transmission resolution (S332).

  Next, the log image generation unit 28b selects a smaller value from the value obtained in S331 and the value obtained in S332 (S333). Here, if the value obtained in S331 and the value obtained in S332 are the same, the log image generation unit 28b selects the value.

  Next, the log image generation unit 28b determines whether or not the value selected in S333 is negative (S334).

  When the log image generation unit 28b determines in S334 that the value selected in S333 is negative, the absolute value of the value is determined as the minus difference amount F (S335), and the operation illustrated in FIG. Note that the negative difference amount is larger than 0 means that the resolution of the image to be transmitted is lower than the system resolution, and therefore it is necessary to enlarge the resolution of this image when transmitting this image. . Here, the smaller the difference between the resolution of the transmission target image and the system resolution, the smaller the minus difference amount. Therefore, the smaller the minus difference amount, the more the transmission target image is transmitted. This means that the enlargement ratio required to make the resolution higher than the system resolution is small.

  When the log image generation unit 28b determines in S334 that the value selected in S333 is not negative, the log image generation unit 28b determines the minus difference amount F to be 0 (S336), and ends the operation illustrated in FIG. Note that the minus difference amount being 0 means that the resolution of the image to be transmitted is equal to or higher than the system resolution, and therefore it is not necessary to increase the resolution of this image when transmitting this image. . That is, the minus difference amount being 0 means that when transmitting an image to be transmitted, the enlargement ratio required to make the resolution of the image equal to or higher than the system resolution is 1 time.

  As shown in FIG. 14, when the log image generation unit 28b finishes the process of S304, the negative difference amount with respect to the system resolution of the Other transmission resolution of the different image different type broadcast transmission job as the target job, as in the process of S304. O is calculated (S305).

  Next, the log image generation unit 28b determines whether or not the minus difference amount F is equal to or less than the minus difference amount O (S306).

  The log image generation unit 28b determines in S302 that “low level” is set in the log image guarantee level information 27e, determines in S303 that the FAX transmission resolution is equal to or higher than the system resolution, or minus difference amount F Is determined to be equal to or less than the negative difference amount O in S306, the image to be transmitted by FAX is determined as the image that is the basis of the log image 27d (S307). Note that the image to be transmitted by FAX is stored in, for example, the storage unit 27 as a result of the process of S266.

  On the other hand, when the log image generation unit 28b determines in S306 that the negative difference amount F is larger than the negative difference amount O, the log image generation unit 28b determines an image to be transmitted by a communication method other than FAX as an image based on the log image 27d ( S308). Note that an image to be transmitted in a communication method other than FAX is stored in, for example, the storage unit 27 as a result of the processing in S266.

  By operating as described above, the log image generation unit 28b determines an image as a basis of the log image 27d in the different image different type broadcast transmission job as shown in FIG. In FIG. 16, the “guarantee level” column in the “system setting” column indicates the log image guarantee level. As for the value in the “guaranteed level” column, “high” indicates “high level”, and “low” indicates “low level”. The “resolution” column in the “system setting” column indicates the system resolution. The “FAX” column in the “Heterogeneous broadcast transmission resolution” column indicates the FAX transmission resolution. The “Other” column in the “Different broadcast transmission resolution” column indicates the Other transmission resolution. The “base image” column indicates an image that is the basis of the log image 27d. In the value of the “base image” column, “FAX” indicates “image to be transmitted by FAX”, and “Other” indicates “image to be transmitted by a communication method other than FAX”.

  As shown in FIG. 14, when the log image generation unit 28b determines in S301 that the target job is not a different image different type broadcast transmission job, executes the process of S307, or executes the process of S308, An image 27d is generated (S309). Here, when the resolution of the image on which the log image 27d is based is less than the system resolution, the log image generating unit 28b logs the log image 27d so that the resolution of the image on which the log image 27d is based is equal to or higher than the system resolution. The log image 27d is generated after enlarging the image on which the image 27d is based.

  The log image generation unit 28b ends the operation illustrated in FIG.

  As described above, the MFP 20 uses the plurality of types of log images 27d of the different types of different types of broadcast transmission jobs, which are different types of different types of broadcast transmission jobs that transmit different types of images having different colors and resolutions. Rather than generating the log image 27d based on all types of images among the images, the log image 27d based on one type of image selected under a specific condition from the plurality of types of images (S302 to S308) Since it is generated (S309), it is possible to appropriately generate the log image 27d of the different image different type broadcast transmission job without waste.

  Since the MFP 20 generates the log image 27d based on one type of image selected under a specific condition among a plurality of types of images of the different image different type broadcast transmission job, all types of images among the plurality of types of images are generated. Compared to the configuration for generating the log image 27d based on the above, the capacity for storing the log image 27d can be reduced.

  The MFP 20 generates the log image 27d based on one type of image selected under a specific condition among a plurality of types of images of the different image different type broadcast transmission job. Compared with the configuration for generating the log image 27d based on the image to be transmitted, it is possible to generate an appropriate log image 27d according to the conditions. Since the MFP 20 can appropriately generate the log image 27d of the different image / different broadcast transmission job, for example, the MFP 20 can generate the log image 27d in which the OCR processing is performed with high accuracy.

  The specific condition for selecting the image that is the basis of the log image 27d is that the resolution of this image is specified when a transmission target image is transmitted among a plurality of communication methods of different image / different broadcast transmission jobs. That is, it includes a condition for selecting an image to be transmitted in a communication method that requires the smallest enlargement ratio to obtain a resolution equal to or higher than the system resolution (S306). With this configuration, the MFP 20 has the highest enlargement ratio required until the image to be transmitted exceeds the system resolution for generating the log image 27d among the plurality of communication methods of the different image heterogeneous broadcast transmission job. Since the log image 27d based on the image to be transmitted in the small communication method is generated (S309), it is possible to suppress the deterioration of the image quality of the log image 27d.

  Further, the specific condition for selecting the image that is the basis of the log image 27d is a specific communication method among a plurality of communication methods of different image different type broadcast transmission jobs, that is, the resolution of the image to be transmitted by FAX. Includes a condition for selecting an image to be transmitted by FAX (S303). With this configuration, the MFP 20 does not need to enlarge the image to be transmitted by FAX among the plurality of communication methods of the different image heterogeneous broadcast transmission job to the system resolution in order to generate the log image 27d. Since the log image 27d based on the image to be transmitted by FAX is generated, the image to be transmitted by FAX can be prioritized as a basis for generating the log image 27d.

  In addition, the specific condition for selecting the image that is the basis of the log image 27d is that a specific communication method, that is, a specific communication method, that is, when a specific level, that is, “low level” is received by the level receiving unit 28c, A condition for selecting an image to be transmitted by FAX (S302) is included. With this configuration, the MFP 20 generates the log image 27d based on the image to be transmitted by FAX when “low level” is accepted as the level for guaranteeing the log image 27d. Can be prioritized as a basis for generating the log image 27d.

  In the present embodiment, the image forming system 10 is configured such that the job type determination unit, log image generation unit, and level reception unit of the present invention are all provided in the MFP 20. That is, the log image generation system of the present invention is realized as the MFP 20. However, the log image generation system of the present invention may be configured such that at least a part thereof is provided in an apparatus other than the MFP 20 such as the server 30.

  The image forming system 10 includes an MFP as the image forming apparatus of the present invention in the present embodiment, but includes an image forming apparatus other than the MFP, such as a printer dedicated machine, a copy dedicated machine, and a FAX dedicated machine. Also good.
